Why this coupling stands out

The HYD Override design delivers precise braking control without relying solely on vehicle brakes, a real advantage when towing heavier loads or navigating hilly terrain. The combination of a galvanised exterior, anti-rattle screw, and a secure snap-lock mechanism minimizes vibration and movement at highway speeds, helping you maintain stability and reduce wear on both vehicle and trailer.

Ideal use cases

Designed for caravans, heavy trailers, and work rigs that require reliable hydraulic braking with straightforward setup. It’s especially valuable when you tow in variable conditions—from coastal coastal winds to steep mountain grades—where consistent braking response makes a difference in safety and control.

Installation and setup tips

Prepare a sturdy mount using four 12 mm high-tensile bolts aligned with the 182 mm x 54 mm pattern. Ensure the mounting surface is clean and flat to preserve the integrity of the hydraulic line and master cylinder. Confirm the 50mm tow ball compatibility and torque requirements for your bolts to maintain long-term reliability. Because this unit is supplied with a 3/4 inch master cylinder, you’ll have a complete hydraulic override system ready to connect to compatible trailers.
